Hi Steve,

as the discussion in #799345 and upstream in [1] has shown, some fonts --
especially CFF fonts like e.g. fonts-cantarell -- look odd with the new
CFF rendering engine enabled in FreeType, having their vertical stems
smeared independently of the selected hinting method. As it turned
out, the main culprit for this is that the stem darkening feature is
enabled by default in FreeType. Proper support for this feature, however,
requires the actual rendering libraries (e.g. cairo) to have gamma
correction implemented, which they currently do not. Thus, disabling
this feature in FreeType until the rendering stack is fixed to
properly support it appears as the correct way to move forward.

I have prepared a private freetype package with a simple patch
applied to disable this feature. Reportedly, rendering of the affected
fonts is vastly improved with this package installed. Please find it
here:

Thank you!

Cheers,

Fabian
